Product description
A mobile filter integrity test system is a portable platform for performing membrane filter integrity testing directly at filtration installations. The system integrates an integrity testing instrument with a mobile trolley, allowing flexible testing of cartridge filters or membrane filters at different locations within a facility.Technical overview
In many filtration processes, membrane filters must be verified before and after use to confirm their integrity. A mobile test system allows these tests to be carried out directly at the filtration equipment. The system combines an integrity tester, pressure regulation components and connection interfaces within a stable trolley configuration. Depending on the configuration, the system can test a single filter housing or multiple filters simultaneously through a multi-channel setup.Operating principle
The system verifies filter integrity by applying controlled gas pressure to a wetted membrane filter and measuring gas flow or pressure behavior through the filter structure. Typical integrity test methods include:- Forward flow / diffusion testing
- Bubble point testing
- Pressure hold testing
- Water intrusion testing for hydrophobic membranes
Material options
Mobile integrity testing systems are typically constructed from durable industrial materials suitable for laboratory and production environments. Typical materials include:- Stainless steel trolley frame
- Industrial pneumatic components
- Precision pressure sensors
- Chemically resistant tubing and connectors
Available micron ratings
Integrity testing equipment verifies membrane filters across a wide range of filtration grades rather than performing filtration itself. Typical membrane filters tested include:- 0.1 µm sterilizing grade membranes
- 0.2 µm sterile filtration membranes
- 0.45 µm clarification membranes
- Other microfiltration membranes used in industrial liquid filtration
Design and construction
Mobile integrity testing systems combine measurement instrumentation with a mobile trolley platform. Typical design characteristics include:- Mobile trolley with integrated testing instrument
- Pressure control and measurement system
- Connection interfaces for filter housings
- Single-channel or multi-channel testing capability
- Storage space for accessories and adapters
Typical applications
Mobile filter integrity testing systems are commonly used in:- Pharmaceutical sterile filtration validation
